Application of TRIVEXTM II Potary System in the Treatment of Venous Ulcer in Lower Extremity

Objective To investigate the evidence of clinical application of TRIVEXTMII potary system in the treatment of venous ulcer in the lower extremity.Methods The clinical data of 200 cases involving 200 legs with venous ulcer in the lower extremity,who accepted the TRIVEXTM Ⅱ potary system or the percutum transfixion surgical treatment from October 2005 to May 2009,were analyzed and studied.200 cases were randomly divided into group A and group B,In the group A,there were 120 cases involving 120 legs treated with TRIVEXTMII potary system,in the group B,80 cases involving 80 legs were treated with percutem transfixion. The skin infection rate,necrosis rate,shrinkage rate of wound area,skin depigmentation rate,ulcer healing rate and ulcer recurrence rate were observed at 5 day,20 day,120 day and 360 day after the operation respectively. Results The incidence of skin infection and skin necrosis was significantly lower in group A than that in group B at 5 day after operation (P0.05).The rate of shrinkage of wound area and skin depigmentation was significantly different between group A and group B at 20 day (P0.05).The ulcer healing rate was not significantly different between group A and group B at 120 day (P0.05).The ulcer recurrence rate was arkably lower in group A than that in group B at 360 day (P0.05).Conclusions TRIVEXTM Ⅱ potary system can efficiently promote the healing of venous ulcer in the lower extremity,and at the same time it has a ascendancy in reducing the incidence of skin infection and skin reinjury.
